Figure 4

Plots of correlation analyses of the levels of NCS-1 in the DLPFC expressed per neuronal DNA in relation to age, postmortem period (PMI), brain pH, and the lifetime dosage of antipsychotic drugs in fluphenazine equivalents among the cases constituting the Stanley Foundation Neuropathology Consortium. Circles represent values for individual samples. R = correlation coefficient; P = significance. There are no significant correlations between NCS-1 levels and age, PMI, brain pH, and the lifetime dosage of antipsychotic drugs. In contrast, there is a significant negative correlation between the levels of NCS-1 and tissue alkalinity (indicated by the descending line and the asterisk near the appropriate P value).
